Question

A parasil is 1/20 of a meter above the water. Then, after 10 minutes, tge parasil is 1/50 of a meter above the water. What is the change in height?

Answer 1

To find the change in height, we subtract the initial height from the final height.

Given:
Initial height = 1/20 meter
Final height = 1/50 meter

Change in height = Final height - Initial height
Change in height = (1/50) - (1/20)

To subtract fractions, we need to find a common denominator.

Common denominator of 20 and 50 = 100

Change in height = (1/50) - (1/20) = (2/100) - (5/100)

Now that the fractions have the same denominator, we can subtract them.

Change in height = 2/100 - 5/100 = -3/100

So, the change in height is -3/100 meters.
